BINDER ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 764,481, dated July 5, 1904.

Application filed September 19, 1903. Serial No. 173,822. (No model.)

. To all whom, t may concern.' r'

' proved breastplate, the principal feature of which is oney or more traveling members, such as chains, mounted on the breastplate and arranged to run freely under the action of the moving grain, thus relieving the binder of the friction Which takes place during the operation of the ordinary binder. With this breastplate is associated a dog or stop device which holds the grain firmly in place under the breastplate and against the trip-arm, and on the deck of the binder I form a shoulder lying just under the breastplate and facing the trip-arm, the binder-deck having an ineline leading up to this shoulder, so that the grain is forced up along the incline and over the shoulder during the formation of the gavel. This shoulder and incline not only hold the grain firmly in place against the triparm, but they relieve the needle and packers of considerable work, thereby enabling the binder to be run more readily than ordinarily.

This speciiieation is an exact description of one example of my invention, while the claims define the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of my invention. Fig. 2 is a top plan View of the breastplate. Fig. 3 is a bottom plan view, the chains being removed. Fig. 4 is a section on the line 4 11 of Fig. 1. Fig. 5 is a section on the line 5 5 of Fig. 1, and Fig. 6 is a section on the line 6 6 of Fig. 1.

10 indicates the binder-deck, 11 the needle, 12 one of the packers, and 14 the trip-arm,

sired construction.

The breastplate comprises an upper portion 15, from which extend two oblong chainguides 16, spaced from each other to form a passage 17 for the needle. Said upper portion 15 has a cavity 18 in its Linder side, this cavity forming a continuation of the needlecavity 17. The lower portion 19 of the breastplate is formed integral with the chain-guides and has a cavity 2O therein forming a continuation of the cavity 17, through which cavity 20 the knetter device is worked.

21 indicates guide-flanges or guards formed on the under side of the lower part 19 of the breastplate at each side of the chain-guides 16 and serving to prevent the straw from passing up with the chains. The chains 22 are endless and are arranged torun freely around the chain-guides, the bottom runs of the chains lying directly over the deck of the binder, and said chains have the gavel pressed toward them. As the grain moves toward the trip-arm in the formation of the gavel the chains move with the grain, and thus the friction of the grain moving against the breastplate is greatly reduced.

Brackets 23 are attached to the upper portion 15 of the breastplate and project transversely from cach side thereof. Said brackets have pivotally mounted thereon the arms or levers 24, the lower portions of which have teeth 25 formed on or fastened thereto and the upper portions of which are connected by a cross-piece 26, to which springs 27 are applied, these springs tending to throw down the lower ends of the arms 24. These toothed arms bear, therefore, on top of the gavel during the formation thereof, and while they offer practically no resistance to the movement of the grain toward the trip-arm they nevertheless effectively prevent the return thereof.

According to the construction here shown I fasten on the deck of the binder a number of transversely-alined cleats 28, which have their upper edges 28 slanting from the deckline upward to their rear edges 28". Said edges 28 form, therefore, an incline leading up to the lower edges 28h to form a shoulder facing the trip-arm 14.. This shoulder and vss incline may be formed by other means, if desired; but I consider the construction above described preferable, since it is light and reduces the friction on the moving grain. As the grain is advanced by the packers it is pushed along the incline and finally drops down in front of the shoulder, which holds the grain snug and prevents the return thereof, this shoulder then coacting with the dogarms 24. This shoulder also completely separates the gavel from the unformed grain on the upper part of the deck, and when the bundle is formed it may be readily discharged from the machine, the discharge being in this case much easier and freer than heretofore. Further and of equal importance is the fact that the incline holds the grain up from the plane of the deck at the point where the needle passes through, and thus the needle is allowed to assume nearly a vertical position before its heel strikes the grain. This greatly relieves the needle and causes the grain to be forced downward toward the trip-arm instead of upward against the breastplate.

Various changes in the form, proportions, and minor details of my invention may be resorted to at will without departing from the spirit and scope thereof. Hence I consider myself entitled to all such variations as may lie within the intent of my claims. A

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. A binder-breastplate, having a member mounted to slide freely thereon and adapted to be engaged by the grain, for the purpose specified.

2. A binder-breastplate, having an endless chain arranged to run free thereon and to be ngaged by the grain, for the purpose speci- 3. Abinder-breastplate, comprising an oval guide, and an endless chain arranged to run free around the same and to be engaged by the grain.

4. A binder-breastplate, comprising two chain-guides spaced from each other to receive the needle, and a chain arranged to run free on each guide and adapted to be engaged by the grain, for the purpose specified.

5. In a binder, the combination with the breastplate, of a yieldingly-sustained arm at each side thereof, said arlns having teeth there.- on and formingv dogs to prevent the return of the grain.

6. In a binder, the combination of a yieldingly-sustained dog arranged to bear on top of the gavel, and a binder-deck having a transverse shoulder formed thereon and facing the trip-arm.

7. In a binder, the combination of a breastplate, a member arranged to run free thereon and adapted to be engaged by thegrain, for the purpose specified, and a yieldingly-sustained arm on each side of the breastplate, said arms having teeth thereon adapted to engage the gavel to prevent the return thereof.

8. In a binder, the combination of a breastplate, a member arranged to run free thereon and adapted to be engaged by the grain for the purpose specified, a yieldingly-sustained dog arranged at each side of the breastplate and adapted to bear on top of the gavel, and a deck located under the dog and breastplate and having a transverse shoulder thereon facing the trip-arm and forming with the triparm a receptacle for the gavel.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ALBERT MARTIN DAVIS.
